Fig. 6: Allometry aligns with both developmental and evolutionary variance.
From: Macroevolution along developmental lines of least resistance in fly wings
a, Wing shape changes with size across 127 species of flies (spanning 30 different families), indicating allometric scaling of shape (multivariate regression of shape against log centroid size: F1,126 = 18.7, P < 0.001, R2 = 0.13). b, These evolutionary allometric shape changes align with the main axes of developmental and macroevolutionary variance in fly wings. c, These alignments are much stronger than expected by chance. The displacement of relative landmark positioning with an evolutionary increase in wing size is indicated by black arrows in b.
